razer ornata chrome media keys

Hi everyone,

I have problem with media keys on my keyboard ornata chroma. I listen to music on youtube and it worked normally till few days ago play/stop works normaly but buttons for skip track or previous track dont work properly sometimes it works for one song when i skip the track then i can no long skip track. i dont believe it's keyboards fault. I looked some threads on forum but i didn't cross any of them with similar problem.
